Ukuhlolwa kwesimo sempahla yesikole saseKannisto kuqediwe: isistimu yokukhipha umoya iyahogela futhi iyalungiswa

Njengengxenye yokunakekelwa kwezakhiwo zedolobha, ukuhlolwa kwesimo sayo yonke impahla yesikole sase-Kannisto sekuqediwe. Idolobha liphenye isimo sesakhiwo ngosizo lokuvuleka kwesakhiwo kanye namasampula, kanye nokuqapha isimo okuqhubekayo. Ngaphezu kwalokho, idolobha laphenya ngesimo sesimiso sokungenisa umoya kule ndawo. Ukulimala komswakama wendawo kanye nemithombo yefayibha okufanele isuswe kutholwe ophenyweni. Ngosizo lwenhlolovo yokungena komoya kanye nokuqapha isimo esiqhubekayo, kwatholakala isidingo sokushintsha imishini emidala yokukhipha umoya nokuhogela nokulungisa uhlelo lokungenisa umoya.

Ezifundweni zobunjiniyela bezakhiwo, umswakama wezakhiwo waphenywa futhi isimo sazo zonke izingxenye zesakhiwo saphenywa ngokusebenzisa ukuvuleka kwesakhiwo kanye namasampula. Ukuhlolwa kwe-tracer nakho kwenziwa ukuze kutholwe ukuvuza komoya okungenzeka. Izilinganiso zemvelo eziqhubekayo zazisetshenziselwa ukuqapha izilinganiso zokucindezela kwesakhiwo maqondana nomoya wangaphandle nendawo engaphansi, kanye nezimo zomoya wasendlini ngokwesikhutha, izinga lokushisa kanye nomswakama. Ngaphezu kwalokho, ukugxilwa kwezingxube ze-volatile organic organic compounds (VOC) kukalwa emoyeni wasendlini, futhi kwaphenywa ukugxila kwezintambo zoboya bamaminerali. Kwaphenywa nesimo sesistimu yokukhipha umoya.

Umgomo wedolobha uwukushintsha imishini emibili emidala yokukhipha umoya esefinyelele ekupheleni kwenkonzo yayo, kanye nokuhlola nokulungisa yonke indlela yokungena komoya yendawo phakathi neminyaka ka-2021-22. Okunye ukulungiswa okutholakala ekuhlolweni kwesimo kwenziwa ngokuhambisana neshejuli ngokuvumelana nohlelo lokulungisa nangaphakathi kwesabelomali.

Endaweni yesikole i-Kannisto, inkulisa i-Niinipuu ne-Trollebo daghem isebenza engxenyeni endala eyakhiwa ngo-1974, kanti i-Svenskbacka skola engxenyeni enwetshiwe eyaqedwa ngo-1984.

Umonakalo womswakama wendawo ubonwe esakhiweni

Ukushoda kwendawo kutholwe ekuphathweni kwamanzi emvula ngaphandle kwebhilidi. Akukho ukuvimbela amanzi noma ibhodi ledamu elatholakala esakhiweni se-plinth, futhi amanani omswakama ongaphezulu we-plinth ayephezulu eduze kwamapulatifomu okungena, ebangeni elingaba ingxenye yemitha ukusuka eminyango yangaphambili. Umswakama wendawo kanye nokulimala kokubola kutholwe kuphaneli yodonga oluphansi kunazo zonke odongeni lwangaphandle lwesikhala esixhunywe ekilasini lomsebenzi wezobuchwepheshe wengxenye endala, elungiswayo.

Isakhiwo sinesakhiwo se-subfloor esingena umoya, okuwukhuni engxenyeni endala kanye nokhonkolo owenziwe ngaphambili engxenyeni yokunwetshwa. Ekuphenyweni, kutholakale esakhiweni saphansi ukuthi kunomswakama owandayo ezindaweni, ikakhulukazi eduze neminyango yangaphandle kanye nodonga oluphambene nesiqandisi sasekhishini. Ukukhula kwe-microbial kwatholakala kumasampula woboya bamaminerali athathwe ekuvulekeni kwesakhiwo se-sub-base yengxenye endala. Ingxenye yesandiso ifakwe i-polystyrene, engenakuthinteka ekulimaleni.

"Ezivivinyweni zomaka, amaphuzu avuzayo atholakale ekuxhumekeni kwesakhiwo sezingxenye ezahlukene zesakhiwo. Akukho ukuxhumana okuqondile komoya osendlini kusukela ekufakweni kwengxenye endala yesakhiwo esingaphansi, kodwa kungenzeka ukuthi ukungcola kungene emoyeni ongaphakathi ngokuvuza,” kusho u-Ulla Lignell, uchwepheshe wezemvelo wasendlini wedolobha laseKerava. "Lokhu kuvame ukuvinjelwa ngokulungiswa kokutywinwa. Ngaphezu kwalokho, izimo zomoya zasendlini zilawulwa ukucindezela okungekuhle kwe-undercarriage."

Kumasampuli amahlanu athathwe esakhiweni sikakhonkolo sesitezi sesandiso, isampula elilodwa elisuka egumbini lokubhalela libonise ukugxila okuphakeme kwezinhlanganisela eziphilayo ezishintshashintshayo (VOC).

“Ezilinganisweni ezithathwe egumbini lokubhalela, akutholwanga ukuswakama okungavamile,” kuqhuba uLignell. “Kunokhaphethi wepulasitiki egumbini lokugqoka, lona ngokwalo eliwugqinsi. Yebo, iphansi lepulazi lidinga ukulungiswa, kodwa isidingo sokulungisa asisibi kakhulu."

Umswakama endaweni yokushisa yezindonga zangaphandle wawusezingeni elivamile. Umswakama ongavamile wabonwa kuphela engxenyeni engezansi yodonga lwangaphandle lwesitoreji semishini yangaphandle. Ngaphezu kwalokho, ukukhula kwama-microbial kwabonwa ezindaweni ezihlala zodwa.

“Futhi, izikhala ezivalekile zezindonga zangaphandle azixhumene ngqo nomoya ongaphakathi, kodwa amagciwane angathuthelwa emoyeni wasendlini ngokusebenzisa izindawo ezivuzayo zamalunga esakhiwo,” kusho uLignell. "Izinketho zokulungisa kungaba ukuvala amalunga esakhiwo noma ukuvuselela izinto zokufaka izinto."

Njengengxenye yezilinganiso zomswakama, ukulimala komswakama kanye nomphumela wokukhula kwamagciwane kubonwe ekuphenyweni kwesiqandisi esakhiweni sodonga phakathi kwesiqandisi nendawo eseduze, okungenzeka ukuthi imbangela yakho ukuntula kobuchwepheshe bomswakama. Ukusebenza kwesiqandisi kuyaphenywa futhi isakhiwo sodonga esonakele siyalungiswa.

Imithombo ye-fiber ikhishwa ophahleni bamanga

Njengengxenye yocwaningo, ukugxilwa kwezintambo zoboya bamaminerali kwahlolisiswa futhi uvolo wamaminerali ongagcotshiwe watholakala kwezinye zezakhiwo zophahla ezimisiwe, ezingakhulula imicu emoyeni wasendlini. Ezindaweni eziyishumi ezihloliwe, indawo yokudlela kuphela etholwe inemicu yamaminerali amaningi kunomkhawulo wokwenza. Ngokunokwenzeka, imicu iphuma ku-mineral wool insulation of the sub-ceiling structure noma kuma-acoustic panel. Kungakhathaliseki ukuthi imvelaphi, imithombo ye-fiber yophahla oluphansi iyasuswa.

Uphahla lwamanzi lwesakhiwo lusesimweni esigculisayo. Uphahla lwengxenye endala lunezimbobo ezindaweni futhi upende wekhava yamanzi wehholo lezemidlalo uphume cishe yonke indawo. Uhlelo lwamanzi emvula ophahleni lusesimweni esigculisayo. Ophenyweni, ukuvuza kutholwe kwezinye izindawo lapho kuxhunywa khona imisele yamanzi emvula, kanye nendawo evuzayo lapho kuhlangana khona ama-eaves engxenye endala kanye nengxenye enwetshiwe. Iphuzu lokuvuza liyalungiswa futhi amalunga omsele wemvula avaliwe.

Isistimu yokungenisa umoya iyahogela futhi ilungiswe

Kunemishini eyisithupha ehlukene yokukhipha umoya esakhiweni, emithathu yayo – ikhishi, igumbi lezingane zasenkulisa kanye nenkantini yesikole – misha futhi isesimweni esihle. Iyunithi yokungenisa umoya efulethini langaphambili nayo yintsha sha. Imishini yokukhipha umoya ekugcineni kwamakilasi esikole kanye nekhishi lenkulisa midala.

Umshini wokungenisa umoya emakilasini esikole unemithombo yefayibha futhi ukuhlunga komoya ongenayo kuba buthaka kunokujwayelekile. Kodwa-ke, ukugcina umshini kunzima, isibonelo ngenxa yenani elincane lama-hatches okuhlola, futhi umthamo womoya uhlala uncane. Umthamo womoya ezikhungweni zokunakekela izingane uhambisana namanani okuklama. Kodwa-ke, cishe kunemithombo yemicu endaweni yokungenisa umoya ekugcineni kwekhishi esikhungweni sokunakekela izingane.

Uma lokhu kanye nesikhathi sokuphila semishini emidala kucatshangelwa, kunconywa ukuvuselela imishini yokukhipha umoya, kanye nokuhlanza zonke izinhlelo zokungenisa umoya bese kulungiswa umthamo womoya. Idolobha lihlose ukwenza ukuhogela kanye nokususwa kwemithombo yefayibha ngo-2021. Ukuvuselelwa kwemishini emibili emidala yokukhipha umoya kufakwe ohlelweni lokulungisa isakhiwo iminyaka engu-2021-2022.

Ngosizo lwezilinganiso zemvelo eziqhubekayo, izilinganiso zokucindezela kwesakhiwo ngokuphathelene nomoya wangaphandle kanye ne-subspace zazibhekwa, kanye nezimo zomoya wangaphakathi mayelana ne-carbon dioxide, izinga lokushisa kanye nomswakama. Ukwengeza, ukugxila kwe-volatile organic compounds (VOC) kukalwa emoyeni wangaphakathi.

Ngokwezilinganiso, ukugxila kwe-carbon dioxide kwakusezingeni eligculisayo, ngokuhambisana nezinga eliqondiwe ngesikhathi sokwakha. Ukugxiliswa kwezinhlanganisela ze-organic organic (VOC) emoyeni wasendlini bekungaphansi kwemikhawulo yesenzo ezilinganisweni.

Ezilinganisweni zomehluko wengcindezi, izikhala esakhiweni zazisezingeni eliqondiwe isikhathi esiningi, ngaphandle kwendawo yokuzivocavoca yesikole nendawo eyodwa enkulisa. Umehluko wengcindezi uyalungiswa lapho kulungiswa uhlelo lokungenisa umoya.

Ngaphezu kwezifundo zesakhiwo kanye ne-ventilation, izifundo zesimo zamapayipi nezinhlelo zikagesi nazo zenziwa esakhiweni, kanye nokuhlolwa kwe-asbestos nezinto eziyingozi, imiphumela esetshenziselwa ukuhlela ukulungiswa kwendawo.
